Keeps the old name around for backwards compat.
Closes #20840
|
|
|
|
This brings in [`display`](https://github.com/rgbkrk/display.js) as part
of the `Deno.jupyter` namespace.
Additionally these APIs were added:
- "Deno.jupyter.md"
- "Deno.jupyter.html"
- "Deno.jupyter.svg"
- "Deno.jupyter.format"
These APIs greatly extend capabilities of rendering output in Jupyter
notebooks.

Closes https://github.com/denoland/deno/issues/20750
This matches what browsers do:
https://developer.mozilla.org/en-US/docs/Web/API/Window/name
In the future we might want to change the behavior to actually update
the process name, but that needs a bit of discussion regarding if
it needs a permission flag (that would make polyfiling `process.title`
setter really easy too).

module (#20800)
Adds a `referrer` parameter to this function instead of using a fake
one.

`readSync()` (#20792)
Closes #20701
|
|
Adds `buffers` to the `Deno.jupyter.broadcast` API to send binary data
via comms. This affords the ability to send binary data via websockets
to the jupyter widget frontend.

managed `CliNpmResolver` (#20777)
Part of https://github.com/denoland/deno/issues/18967

(#20714)
Exposes
[`metadata`](https://jupyter-client.readthedocs.io/en/latest/messaging.html#metadata)
to the `Deno.jupyter.broadcast` API.
```js
await Deno.jupyter.broadcast(msgType, content, metadata);
```
The metadata is required for
[`"comm_open"`](https://github.com/jupyter-widgets/ipywidgets/blob/main/packages/schema/messages.md#instantiating-a-widget-object-1)
for with `jupyter.widget` target.

This makes `CliNpmResolver` a trait. The terminology used is:
- **managed** - Deno manages the node_modules folder and does an
auto-install (ex. `ManagedCliNpmResolver`)
- **byonm** - "Bring your own node_modules" (ex. `ByonmCliNpmResolver`,
which is in this PR, but unimplemented at the moment)
Part of #18967

This is required from BYONM (bring your own node_modules).

This API is providing hoops to jump through with undergoing migration to
`#[op2]` macro.
The overhead of supporting this API is non-trivial and besides internal
use of it in test sanitizers is very rarely used in the wild.

Removes usage of `serde_json::Value` in several ops used in TSC, in
favor of using strongly typed structs. This will unblock more
changes in https://github.com/denoland/deno/pull/20462.

This PR implements a graceful shutdown API for Deno.serve, allowing all
current connections to drain from the server before shutting down, while
preventing new connections from being started or new transactions on
existing connections from being created.
We split the cancellation handle into two parts: a listener handle, and
a connection handle. A graceful shutdown cancels the listener only,
while allowing the connections to drain. The connection handle aborts
all futures. If the listener handle is cancelled, we put the connections
into graceful shutdown mode, which disables keep-alive on http/1.1 and
uses http/2 mechanisms for http/2 connections.
In addition, we now guarantee that all connections are complete or
cancelled, and all resources are cleaned up when the server `finished`
promise resolves -- we use a Rust-side server refcount for this.
Performance impact: does not appear to affect basic serving performance
by more than 1% (~126k -> ~125k)

The test is just `b.start(); b.end()` where the time measured between
must be less 10 μs during warmup. Can't improve it.
Also fixes doc mistake.

Disables `BenchContext::start()` and `BenchContext::end()` for low
precision benchmarks (less than 0.01s per iteration). Prints a warning
when they are used in such benchmarks, suggesting to remove them.
```ts
Deno.bench("noop", { group: "noops" }, () => {});
Deno.bench("noop with start/end", { group: "noops" }, (b) => {
b.start();
b.end();
});

Few improvements to FFI types:
1. Export `PointerObject` for convenience. It's fairly commonly used in
library code and thus should be exported.
2. Fix various comments around `PointerValue` and `UnsafePointer` and
expand upon them to better reflect reality.
3. Instead of using a `Record<"value", type>[T]` for determining the
type of an FFI symbol parameter use direct `T extends "value" ? type :
never` comparison.
The last part enables smuggling extra information into the parameter and
return value string declarations at the type level. eg. Instead of just
`"u8"` the parameter can be `"u8" & { [brand]: T }` for some `T extends
number`. That `T` can then be extracted from the parameter to form the
TypeScript function's parameter or return value type. Essentially, this
enables type-safe FFI!
The foremost use-cases for this are enums and pointer safety. These are
implemented in the second commit which should enable, in a backwards
compatible way, for pointer parameters to declare what sort of pointer
they mean, functions to declare what the API definition of the native
function is, and for numbers to declare what Enum they stand for (if
any).

Fixes https://github.com/denoland/vscode_deno/issues/856.

This commit adds new "--deny-*" permission flags. These are complimentary to
"--allow-*" flags.
These flags can be used to restrict access to certain resources, even if they
were granted using "--allow-*" flags or the "--allow-all" ("-A") flag.
Eg. specifying "--allow-read --deny-read" will result in a permission error,
while "--allow-read --deny-read=/etc" will allow read access to all FS but the
"/etc" directory.
Runtime permissions APIs ("Deno.permissions") were adjusted as well, mainly
by adding, a new "PermissionStatus.partial" field. This field denotes that
while permission might be granted to requested resource, it's only partial (ie.
a "--deny-*" flag was specified that excludes some of the requested resources).
Eg. specifying "--allow-read=foo/ --deny-read=foo/bar" and then querying for
permissions like "Deno.permissions.query({ name: "read", path: "foo/" })"
will return "PermissionStatus { state: "granted", onchange: null, partial: true }",
denoting that some of the subpaths don't have read access.
Closes #18804.

This commit stabilizes "Deno.serve()", which becomes the
preferred way to create HTTP servers in Deno.
Documentation was adjusted for each overload of "Deno.serve()"
API and the API always binds to "127.0.0.1:8000" by default.

This PR changes Web IDL interfaces to be declared with `var` instead of
`class`, so that accessing them via `globalThis` does not raise type
errors.

Relands #19463. This time the `ExtensionFileSourceCode` enum is
preserved, so this effectively just splits feature
`include_js_for_snapshotting` into `exclude_js_sources` and
`runtime_js_sources`, adds a `force_include_js_sources` option on
`extension!()`, and unifies `ext::Init_ops_and_esm()` and
`ext::init_ops()` into `ext::init()`.

|
Extend the unstable `Deno.Kv` API to support queues.

(#19490)
… (#19463)"
This reverts commit ceb03cfb037cf7024a5048b17b508ddda59cfa05.
This is being reverted because it causes 3.5Mb increase in the binary
size,
due to runtime JS code being included in the binary, even though it's
already snapshotted.
